# AdBlue in a Diesel Tank in Fosters Green? Don't Start It

AdBlue in your diesel tank? Then leave the motor off — and the ignition too.

Water with urea dissolved in it: that is AdBlue.

Not like fuel, it neither burns nor blends, and no harm happens till the motor sucks it round.

A drain and a thorough flush, done where the vehicle is in Fosters Green, is normally all AdBlue in a diesel tank needs — if it is caught before the motor has run.

Before you do anything else, call 0333 366 0103.

## AdBlue in your diesel tank around Fosters Green: the first few minutes

Things to do:

- So nobody can switch the ignition on, pull the keys away.

- Near moving traffic? So put the hazards on.

- Which product, and roughly what quantity? Hang on to the bottle or the till receipt, and our engineers can know.

- Tell us a postcode starting WN8 6, or whatever street is closest, and our van reaches you directly — so ring from wherever you stand.

Things not to do:

- No starting the motor — not briefly, not to shift the car.

- Your ignition remains off: on lots of diesels, turning it on is enough to run your pump.

- Adding more diesel doesn't help: AdBlue separates out rather than thinning.

- Even a short way down Birch Green Road is too far to drive the vehicle.

- Draining your tank yourself beside the road isn't worth trying.

Moving your car off the island is a job for attendants to help with, whichever Fosters Green forecourt you're on, the Asda included.

If you are on your own drive, leave the vehicle exactly where it is.

## AdBlue in a diesel tank, and what it does there

Not your motor but your exhaust is where AdBlue belongs.

It goes into its own tank and is sprayed into the exhaust gas to fresh it.

A fuel pump isn't designed to cope with it, and AdBlue was never supposed to go through one.

It does not blend. Once it is tipped into the tank, AdBlue acts nothing like fuel.

The intake sucks fuel from the lowest part of the tank, and that is precisely where AdBlue ends up: as it is heavier than diesel, it sinks.

Easiest of all: one that had AdBlue in Dalton last night and hasn't turned since. The liquid sits at the base of that tank, untouched — though it would be the first thing through if the engine runs, ahead of any diesel at all.

Two kinds of damage follow from there.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, so it keeps working on the parts it hits for as long as it stays there.

Where the AdBlue is in the pipework, leaving it till morning around Fosters Green makes things worse. In your tank only, waiting does nothing.

Then there's the water: it offers no lubrication to the components that need it the most — the injection pump and every injector.

## Why is AdBlue in a diesel often the bigger problem?

A fault of thin fuel is what you get after filling a diesel with petrol at the Shell.

No harm comes as long as it stays put, mixed into the diesel — only once the engine runs on it.

AdBlue in a diesel is another matter: not thin fuel, but no fuel at all.

Since it doesn't burn, running it through isn't an option.

It does not stay mixed, and so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting your motor "to see" costs more here than almost anywhere else, whether the vehicle is in Tanhouse or the middle of Fosters Green.

As with petrol, there's good news.

If your engine hasn't run, the AdBlue is still inside the tank, and that tank is the simplest part of a fuel system to clear, wherever across Lancashire the car is standing.

## AdBlue in a diesel tank in Fosters Green: how it ends up there

In dim light, two caps together — the AdBlue cap and the diesel one, now and then behind a single flap — can appear the same. No one intends it; plenty of designs invite it.

A container picked up while driving home and tipped in outside the house, rather than at the filling station, is the usual route.

It tends to occur in a couple of familiar ways.

The refill is rushed outside Woodland Community Primary School, because your dash flashed with a warning while the kids were taken in.

A bottle is poured in at the end of the day on a drive just off Helmsdale.

Or someone new to that flap refills your vehicle in dim light, stopped in the car park by The Beacon (closed).

It occurs most in the motors motorists know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol.

Wherever around Lancashire, Fosters Green as well, the mistake doesn't change, and neither does the first response: leave it switched off.

## Started the motor with AdBlue in the diesel tank around Fosters Green?

Then the AdBlue has left the tank.

It has been sucked through the fuel filter and your lines, and if your engine ran for any time, it has reached the high-pressure fuel pump and the injectors.

Rough running, smoke from the exhaust, lost power, dashboard warnings or cutting out: each might appear, maybe midway across Fosters Green or coming back from Skelmersdale Henge Park.

Stop as soon as it is safe, switch off, and do not restart the car to check.

More of that is pulled through with each start.

If you were on the M58, under 3 miles from Fosters Green, come off at the next exit and stop somewhere sensible instead of pressing on.

Distance counts: each mile pushes the AdBlue further into your system, so driving towards Liverpool, under 15 miles away, makes a much larger job than crossing Fosters Green to the car park by Birch Green Community Centre.

Approximately how far had it come? Tell us.

Wherever the car came to a halt is where all of it gets done, even with more to rinse out once your engine has been run.

Long-term damage is very rare if it is caught soon.

## Fosters Green: how AdBlue is drained from a diesel

Our engineers come to your car, wherever it has stopped in Fosters Green: a side street close to Skelmersdale Henge, a drive, a lay-by or a forecourt.

Before anything else our engineers ask what got in, about how much, and if the engine has been run, since those answers determine the work.

The contaminated diesel and the urea leave as one after that tank is drained, right there.

The fuel system is purged thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own.

A test of your car follows last, after clean diesel is added and the fuel filter is flushed or, if needed, swapped.

If your engine has not run, most jobs take about half an hour once our engineers are there.

Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough to spare the street at night.

The final step is to bleed your system on clean diesel.

Starting the car comes next, and then you head off from where the vehicle is parked, outside Upholland or on a drive in Fosters Green.

It's checked on new diesel to confirm it runs properly before our engineers head off.

Since the job is done in its entirety where your car is, a workshop never comes into it.

You receive a VAT invoice and an engineer report afterwards, which is what insurers ask for.

## What AdBlue in a diesel tank costs to put right in Fosters Green

Each job differs, so no fixed price is honest.

The price changes first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that got in. After that it depends on where the car is and whether a van can get to it safely, which is simpler on an open driveway than in a tight gap behind Ashurst Centre.
